Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are supplied, so the description carries the full behavioral burden. It mentions high/low row ordering but does not disclose default limit behavior, tie handling, null handling, or the shape of the returned rows, which are important for a ranking tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The definition is a single front-loaded sentence with no filler. The embedded quotation is slightly awkward, but the core meaning is delivered efficiently.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no annotations and no output schema, this three-parameter tool needs more detail than the description provides. Key operational facts such as the default limit, the 50-row maximum, how ties are broken, and what the returned rows look like are missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 33%, and the description does not mention the limit parameter at all. It adds some meaning for column by specifying it must be numeric and restates the highest/lowest direction, but it leaves a third of the parameters effectively undocumented beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific operation: return the highest or lowest rows of the named dataset ordered by a numeric column. That is a clear verb-plus-resource purpose, though it does not explicitly differentiate itself from siblings such as dataset_search or dataset_stats.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The quoted "which is the most/least X" gives an implied use case, but there is no explicit guidance on when to choose this tool over dataset_search, dataset_compare, or dataset_stats. It also gives no exclusions or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
